KNOCKDOWN UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 750,178, dated January 19, 1904.

' Application filed June 3, 1902. Serial No. 110,052. (No model-L To all whom it may concern.-

Be it known that I, HERMAN FESENFELD, a

. citizen of the United States, and a resident of Hoquiam, in the county of' Chehalis and State of Washington, have invented new and useful Improvements in Knockdown Umbrellas,'of which the following is a full, clear, and exact description.

My invention relates to umbrellas, my object being moreparticularly toproduce an umbrella which can be readily taken apart or put together and which is simple in its action, strong, cheap, and durable. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a fragmentary section showing my improved umbrella. Fig. 2 is a fragmentary section, somewhat enlarged, showing one end of the central staff and parts appertaining thereto. Fig. 3 is aview somewhat similar to Fig. 2, showing the parts in position for removing the ribs. Fig. 4 is an invertedplan view of the disk 6 shown in Fig. 3. Fig. 5

- is a fragmentary section of the device for holding the inner ends of the ribs. Fig. 6 is a plan View of the disk 17 shown in Fig. 3. Fig. 7 is a detail View showing one 'of the hooks and eyelets whereby the cloth covering is secured upon the outer ends of the ribs, and Fig. 8 is a fragmentary section showing a sliding head from which the stays radiate to the ribs.

'Acentral staff 1 is threaded at its upper end 2, and upon the threaded portion is mounted a ferrule 3, provided with a rounded end 4 and with a flange 5. A disk 6 is provided with apertures consisting of hemispherical portions 7 and the slots 8. The covering, preferably of cloth, is shown at 9. The disk 6 is rigidly secured upon the thimble 10, which is provided at its bottom with an annular flange 11. Concentric to this disk is a bottle-shaped thimble comprising the neck 12 and the enlarged portion 13, and this bottle-shaped thimble is separated from the thimble 10 by the spiral spring 14, as indicated more particularly in Figs. .2 and 3. Upon the thimble 10 is rigidly mounted a boss 15, which engages the slots 16 in the neck 12. Another disk, 17, is provided with apertures consisting of slots 18 and cavities 19, the shapeiof these slots and cavities being shown more particularly in Figs. 2, 3, and 6'.

The ribs of the umbrella are shown at 20 and may be provided with ball-joints 2l,which engage the apertures, as indicated in Fig; 2. By merely forcing the thimble 13 downward,

as indicated in Fig. 3, any one or more of the ribs may be removed and, if desired, other ribs placed in 'thepositions vacated by them.

Adjacent to the outer end'of each rib 20 is a hook 22, preferably ofthe shape indicated in Fig. 7 Near the outer edges ofthe cloth or covering are eyelets 23, which may be brought into engagement with the hooks 22, as indicated more particularly in Fig. 7. When a rib is removed from its mountings, as above described, it may be readily detached from the v cloth by merely pulling the eyelet 23 over the hook 22. By means of the pivot 24 the outer ends of the stays 25 are connected with the ribs in the usual manner.

' In the modification shownin Fig. 8 the disk 1 In Fig. 5 are shown the connections for the inner ends of the stays 25.

The sleeve 33 is of substantially the same form as the sleeve 10, already described. The disk 34 is of the form indicated in Fig. 5, being provided with slots 35 and with hemispherical apertures into 37 is rigidly mounted upon the sleeve 38, so that the entire structure shown in Fig; 5 is quite analogous to that shown in Figs. 2 and 3, with the exception that the stays 25 radiate upward, whereas the ribs 20 radiate horizontally and downward. The sleeve 33 is secured rigidly to the disk 37 and is provided with a slot 32, which engages a spring-catch 41 in the usual manner.

The operation of my device is as follows: The parts being in the position indicated in Fig. 1, suppose that the owner of the umbrella desires to remove one of the ribs which has been accidentally broken. He pulls the sleeve 13 downward, whereupon the parts adjacent to the sleeve assume the position indicated in Fig. 3. He then removes the inner end of the rib. He next pulls the sleeve 38 upward, thereby separating the disks 34 and 37, thus removing the inner end of the stay 25. He next disengages the hook 22 at the extreme outer end of the rib, thus leaving the rib and stay completely separate from the other parts of the umbrella. In inserting a new rib and stay he merely slips the eyelet 23 over the hook 22 and connects the inner end of the rib with the disks 6 and 17 and connects the free end of stay 25 with the disks 34 and 37. If the ball-joint is used, as indicated in Fig. 2, it is merely inserted between the disks, which are then forced together automatically by the action of the spring 14. If the ribs are provided with hooks, as indicated in Fig. 8, the hooks are simply connected with the pivotring 28, while the disks are held asunder. The sleeve contains spring mechanism 39 identical with that already illustrated in Figs. 2 and 3 and is arranged as shown generally in Fig. 1. A second description of the spring is therefore unnecessary.

It will be noted that the disks 6 and 17 constitute a central head practically stationary, while the disks 34 and 37, together with their immediate connections, constitute a sliding head normally free to travel along the staff.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1 1. In an umbrella, the combination with a stick, of a thimble mounted upon the stick and having a flange at one end, a disk secured to one end of the thimble and provided with bearings, a second thimble mounted to slide on the first thimble and having one end enlarged to form an annular space between it and the first thimble, a coiled spring in the space between the thimbles and having its ends bearing on the flange of the first thimble and the shoulder formed by the enlargement of the second thimble, and a disk secured to the second thimble and engaging the first disk, as set forth.

2. In an umbrella, the combination with a stick, of a thimble mounted upon the stickand having a flange at one end, a disk secured to one end of the thimble and provided in one face with recesses having hemispherical inner portions, a second thimble mounted to slide on the first thimble and having one end enlarged to form an annular space between it and the first thimble, a coiled spring in the space between the said thimbles, and having its ends bearing on the flange of the first thimble and the shoulder formed by the enlargement of the second thimble, and a disk secured to the end of the second thimble and provided with radial slots terminating at their inner ends in cavities, as set forth.

3. In an umbrella, the combination with a stick, of a thimble mounted upon the stick and provided with an outwardly-projecting flange at its lower end and with a stud intermediate its ends, a disk secured to the upper end of the thimble and provided on its under face with recesses having hemispherical inner portions, a second thimble mounted to slide on the first thimble and having its lower end enlarged to form an annular. space between it and the first thimble, said thimble being provided with a longitudinal slot to receive the stud of the first thimble, a coiled spring in the space between the said thimbles, and having its ends bearing on the flange of the thimble and the shoulder formed by the enlargement of the second thimble, and a disk secured to the upper end of the second thimble and provided with radial slots terminating at their inner ends in cavities, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HERMAN FESENFELD.
